Abstract (en)
[origin: EP1918453A1] A seam felt 10c for papermaking comprises wet paper web side batt layer 30c and seam region 12. Fragments of a sheet-shaped nonwoven fabric 40a, which is disposed at a region of the wet paper web side batt layer 30c adjacent to the seam region 12, and which is crushed by means of needle punching, are dispersed within the widthwise range of the batt layer. At least a part of the fibers of the batt layer penetrates holes of the fragments of nonwoven fabric 40a, and the fragments of nonwoven fabric 40a are melted by heat and adhere to fibers of the batt layer.
